Just an FYI in case you're looking for these from overseas vendors, lots of the rest of the English-speaking world refers to these as "Braces" (like the things you put on your teeth). They generally seem popular with older riders who wear heavy leather trousers and want something that'll hold the weight of them up, without needing to be so tight around the stomach.

+1 on these Klim suspenders. I was having some "pants on the ground" issues with my RP3 pants(they are heavy). Looked at Walmart and every other cheap option but nothing was the right quality. These Klim suspenders are a quality, heavy duty product and solved the issue.
